Liners, shadows, and mascaras can end up looking like a hot (smudged) mess at the end of the day if you don't use a good primer. Keep on your eye makeup with these reader faves

Best Eye Primer No. 11: Urban Decay Eyeshadow Primer Potion, $20 TotalBeauty.com average member rating: 8.7*Why it's great: Readers say this primer "adds a subtle sheen and color for a nice glow." It is an "absolute go-to holy grail of eye shadow primers," swears one. One reviewer says she can "work all day, work out, sweat like a pig and [her] eye shadow will stay put" with this primer.

I disagree w/the opinion that primers are a waste unless one has oily eyelids. I have extremely dry skin and I have to use a primer for there to be no creases, no crepeyness, & for shadows to have staying power.
